WARNING: This page is about a different car, the 2012 GMC Yukon, 2012 Chevrolet Tahoe, and 2012 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the drive motor generator control module from the vehicle. Refer to Drive Motor Generator Control Module Assembly Replacement .
- Remove the accessory DC power control module ground strap bolt (1) and ground strap (2).
- Remove the temporary coolant pipe caps (1).
- Drain the drive motor generator control module assembly of residual coolant by applying 30 psi regulated compressed air to the coolant inlet pipe until no coolant remains.
- Remove the drive motor generator power inverter control module cover fasteners (1).
- Remove the power inverter module cover (2). Discard the cover seal (3).
- Remove the high voltage dc accessory DC power control module terminal fasteners (1) utilizing a magnetic socket.
- Temporarily install the power inverter module cover (2) with 4 finger-tightened fasteners (1).
- Rotate the drive motor generator control module assembly onto the power inverter module cover.
- Remove the accessory DC power control module to power inverter module mounting fasteners (1).
- Remove the accessory DC power control module (2) and discard the coolant seal (3).
CAUTION:
The module must be drained of all residual coolant prior to disassembly. Failure to properly drain all residual coolant may cause electronic circuit damage to occur during disassembly.
NOTE:
Place a container under the coolant outlet pipe to capture the escaping coolant.
CAUTION:
Always remove and install the High Voltage terminal fasteners with a magnet tipped socket. Never touch the exposed electronic circuit board surface or components. Dropped fasteners or physical contact may result in electronic circuit board damage.
